Bowl-shaped polycyclic aromatic hydrocarbons or buckybowls which can be considered as substructures of fullerenes or nanotubes display superior characteristics which render them ideal candidates for the application in molecular electronics, material sciences, and nanotechnologies. In this respect functionalized buckybowls are of particular interest due to the possibility to tune precisely required properties. However, synthesis of functionalized buckybowls remains a challenge since the fabrication of distorted bowl systems requires harsh reaction conditions that do not tolerate functional group. Here we present efficient strategy for the direct synthesis of functional buckybowls via fluorine promoted Aryl-Aryl coupling. Our methodology is based on the synthesis of polycyclic aromatic hydrocarbons which already contain all necessary carbon atoms and required functionality in appropriate positions. The following intramolecular condensation leads directly to the desired functionalized bowl-shaped molecule. The strategy presented opens the possibility for facile synthesis of extended functionalized bowls in bulk amounts with close to quantitative yield.
